How to prevent confusion when picking up multiple couriers at the same address?

In this case, the methods to prevent confusion are as follows:

1, indicate the recipient's name and telephone number on the address so that the courier can contact the correct recipient when delivering the goods.

2. Put obvious signs at the door or the receiving place, so that the courier can easily find the receiving place.

Please indicate the recipient's name and telephone number on each package so that the courier can easily identify each package.
